Safety razor



Jan, 9, 1934. A E, FRAND; 1343 173 SAFETY RAZOR Filed Aug. 23, 1932 Patented Jan. 9, 1934 UNITED STATES PATENT OFFICE 1 Claim.

My invention relates to a safety razor.

An object of my invention is to provide a safety razor with which it is not possible to cut ones self, and which will not become clogged with soap or beard while in use.

Another object is to provide a device of the kind stated, with which it is possible to shave close around the nose, and wherein the blade is positively set at the proper cutting angle.

A further object is to provide a safety razor which may be cheaply manufactured, and quickly assembled for use.

Other new and useful objects will be apparent from the following description and accompanying drawing, in which like numerals are employed to, designate like parts throughout.

In the drawing:

Figure 1 is a top view of my device with the parts assembled;

Fig. 2 is a side view of the same;

Fig. 3 is a section on the line 3-3 of Fig. 1;

Fig. 4 is a section on the line 44 of Fig. l, and

Fig. 5 is a plan view of the blade.

The numeral 6 designates the handle of my device with a horizontal flange 7 formed on its upper portion, and with a short threaded portion 8 extending above the flange. A double edged lower guard plate 9 has guard teeth 10 at the end of each blade guarding edge, and has similar guard teeth 10 spaced rather widely between the end teeth. The extreme ends of these teeth 10 are turned upward at slightly less than a right angle to the plane of flange 7.

The guard plate 9 also has a centrally located hole threaded to fit the portion 8 of the handle, and also two upstanding lugs 11 disposed on the central longitudinal line of said plate 9. The ends of the plate 9 are concaved inwardly from each longitudinal edge to provide substantially V-shaped recesses as at 12, which are best shown in Fig. 1.

It is also to be noted (see Fig. 3) that the lower guard plate 9 has its ends beveled as at 9 in the direction of the edges of the notch or recess 12, and toward the rear surface of such plate 9.

Also, from Figure 4, it is seen that such lower guard plate 9 has its upper, or blade supporting surface, curved transversely toward each side edge, and preferably in the arc of a circle,as shown. The advantages of the construction described will be evident hereinafter.

The blade 13 has its ends concaved inwardly from each longitudinal edge to conform with the ends 12 of the guard plate 9, and has a central opening 14 to conform with the threaded portion 8 of the handle, and has also slots 15 corresponding with the lugs 11 of the guard plate 9.

The upper blade guard 16 also has its ends concaved inwardly as at 16 from each longitudinal edge to provide notches or recesses, and 30 has straight guard teeth 1'7 which are spaced the same as those on the lower blade guard 9. This upper blade guard 16 has a centrally located tapped hole to receive the threaded portion 8 of the handle, and also has notches 18 to receive 35 the lugs 11 of the lower guard plate.

Particular attention is directed to the fact that the blade-engaging surface of the upper guard plate 16 is provided with convexly curved end portions 16 (Fig. 3), and shaped in conformity with the bevelled portions 9 of the lower guard plate 9; also, that such blade-engaging surface of said upper guard plate is transversely curved, as at 16 in Fig. 4, to conform to the corresponding blade supporting surface 9 of plate 9. By reason of this construction shown and described (Figs. 3 and 4), the blade 13 will be very firmly supported with both blade guards 9, 16, in snug engagement with the proximate surfaces of the interposed blade 13.

To assemble the device, the blade 13 is placed between the upper and lower blade guards and the entire assembly is screwed down tightly onto the flange '7 of the handle.

As may be seen in Figs. 1 and 4, the assembled 35 relation of the teeth and blade make it impossible for a person to cut himself, the teeth completely protecting the sharp edges of the blade.

It is not possible to clog this razor while shaving as there are no slots or recesses to catch the soap and severed beard,-this being a great advantage over other razors which must oftentimes be taken apart and cleaned while being used, particularly when the shaver has a heavy heard. The proper angle of shaving is always obtained for the reason that the handle must be tightly screwed up before the razor can be used, this being of great advantage over other razors, which when screwed up too tightly will not cut, and when not tightened enough are dangerous. The concaved ends of the blade and guards make it possible to cut around close places, such as for instance around the nose.

The upturned ends of the teeth 10 cover the edge of blade 17 which is held down on the intermediate portions of teeth 10 by teeth 17.

Having thus described my invention, what I wish to claim by Letters Patent is:

A safety razor comprising a handle having a horizontal flange at its upper end, a pair of superposed blade guards seated on the flange and having their ends curved inwardly from their corners to form a recess, the maximum depth of which is along the longitudinal axes of the blade guards, the latter having their guarding edges bevelled to form sharply defined angles, widely spaced guard teeth along said plate guarding edges, the teeth on the upper guard corresponding with those of the lower one, the teeth of the upper guard being straight to form continuations thereof, while the teeth of the lower guard are substantially at right angles ANTONIO E.
